STOVE FOR BURNlNG STRAW, 84.0.

SPECIFICATION forming part ofLetters Patent No. 390,304, dated Cictober 2, 1888.

Application filed March 17, 1858. Serial No. 267,468. (No model.) Patented in Canada January '13, 1888, No.28,347.

To all whom it may concern.-

Be it known that I, THOMAS J. MoBnrnnof \Vinnipeg, in the Province of Manitoba, in the Dominion of Canada, have invented certain new and useful Improvements in Stove Attachments for Burning Straw and other Fuel, (for which I have received Canadian Patent No. 28,347, dated January 13, 1888;) and i do hereby declare that the following is a full,clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure l is a side elevation of a stove and my improved burner attached. Fig. 2 is a front elevation of the same. Fig. 3 is a longitudinal vertical section on line A A, Fig. 2. Fig. 4 is a horizontal section on line B B, Fig. 1. Fig. 5 is a vertical section on line 0 0, Fig. 1; and Fig. 6 isa horizontal sect-ion on line D D, Fig. 1.

My invention relates to the construction of stove attachments for burning straw, &c., as fuel, and has for its obj ectto obtain uniformity in combustion and heat and economize fuel by limiting the gravitation of the fuel in a receptacle to a line whereby it will not intercepta horizontal draft-passage through the combustionchamber, and providing means for keeping said draft-passage clear of ashes during combustion.

My invention consists in certain construction and combination of parts hereinafter described, and pointed out in the claims.

1 is. the outside shell of the stove,which has an oven, 2, provided with doors a.

3 is a wood and coal fire-box at the front of the stove and in the flue between the shell of the stove and lining of the oven.

4 is the side door to said firebox, which is provided with gratebars 5 above an ash-pit, o, to which access is obtained through a door, 7, in the front of the stove.

8 is a smokeoutlet directly over the fire-box, and 9 the flue around the oven, which flue below the oven is divided into two branches, 1) b, and are continued upward into the smokeoutlet 8,which is provided with adamper, 10. \Vhen damper 10 is closed and damper 13 at the back of the oven is opened, the products of combustion will pass around the oven and through the branch fines b b into the smokeflue 8, and when damper 10 is opened and damper 13 closed the products of combustion will pass from the combustion-chaniber, hereinafter described, directly into the smoke-outlet to assist in kindling the fire in said chamher.

1]; is a door closing an opening through which soot and ashes are removed from the fines under the oven.

The entrance to flue 9 is at a threat, 12, in the front of the stove, and said throat connects horizontally with a combustionchamber, l-i, suitably supported on the outside of the stove.

The combustion-chamber supports vertically a straw-fuel reservoir, 15, provided with a door, 0, through which the fuel is inserted either loosely or in bales, or it may be inserted in a removable holder, 24, hereinafter described. The reservoir near the top connects with the smoke-outlet 8, to allow gas and smoke which may have accumulated in the reservoir to escape prior to feeding the reservoir with fuel, and after feeding the connection of the reservoir and smokeoutlet is cut off by closing a damper, 21.

In the front of chamber 1 1 is a drafted trance, 1G, to effect combustion, and said entrance is provided with a damper, 17, which closes under pressure from within the chamber to prevent escape of gas into the apartment.

25 are bars at the top of the combustionchamber to support baled fuel while being burned.

At the bottom of the combustionchamber is a series of oscillating rakes, 18, connected by a handle, 19, to remove debris of combustion when desiring a clear fire. Below the rakes is placed a damper, 20, consisting of two barred sections, adjustable, so that the bars of one section will close the openings in the other section, to prevent an upward draft between the rakes, and when the bars coincide allow ashes, 850., to-fall through into an ash receptacle, 26, below the combustionchamber, and said receptacle may be removable or provided with an opening, 27, to re move ashes.

If desired, the straw fuel may be placed in a receptacle or feeder, 24-, and the feeder inserted in the straw-reservoir 15 through door a, and said feeder is made slightly tapering ICO toward the top and the smaller end perforated to permit gas accumulated in the feeder to escape into the smoke-flue through asmall hole in damper 21, or through the opening. The feeder is filled with fuel through the larger or open end and placed in the reservoir the small end uppermost, so that the fuelwill feed downward of its own gravity to supply combustion.

22 are half-doors or dampers in the throat 12 of flue 9, and they may be closed in part when coal or wood is used in fire-box 3; but when straw fuel is burned in combustionchamber 14 they are opened and adjusted, if desired, to deflect heat to the pot-holes at either side of the top of the stove.

When straw fuel is to be kindled, damper is opened, and damper 13 may be closed to obtain direct draft through entrance 16, combustion-chamber 14, and smokeoutlet 8, and afterward said dampers are manipulated to conduct the products of combustion around the oven.

It will be observed that in this construction of attachment the air draft is across the direc tion in which the straw fuel feeds; hence that fuel will be but slowly consumed, as it does not intercept the draft-passage between bars 25 and the rakes 18, and the consumption of fuel and the degree of heat obtained will be uniform. By working the handle 19 of rakes 18 and opening damper 20 by pulling the.

sliding section, the draft-passage between the rakes and the bars will be cleared of ashes, the ashes passing through the bars of the grate into the ash-receptacle 2G. The grate is then closed to prevent upward draft, and the horizontal draft through the combustion-chamber regulated by the adjustment of damper 17. As

the bars 25 limit the gravitation of unconsumed fuel, no fuel can intercept the draftpassage, and hence the consumption will be uniform and the degree of heat correspond thereto.

I claim as my invention 1. In a straw-burning attachment for stoves, the combination of a combustionchamber having smoke and draft openings horizontally opposite, fuel-supporting bars level with the top of said openings, and oscillating rakes pivoted level with the bottom of said openings,whereby the fuel will not intercept the draft and the rakes clear the draft-passage of ashes, a damper having a sliding section to shut off upward draft, and,when desired, permit ashes to fall through, an ash-receptacle below the grate, and a fuel-receptaele standing on the upper edge of the combustion-chamber, as set forth.

2. In a straw-burning attachment for stoves, the combination of a combustion-chamber,14, having a smoke-outlet, 12, and draftinlet 16 horizontally opposite, the fuelsupporting bars 25 level with the top of said outlet, the oscillating rakes 18, pivoted level with the bottom of said inlet, a damper, 20, below said rakes and provided with a sliding section to shut off draft through the bars, the ash-chamber 26 below the grate, and a fuel-reservoir, 15, supported by the upper edge of the combustion- 7o chamber, and having a door, 0, and an opening near the top provided with a damper, 21, as and for the purpose set forth.
